Mitsubishi RISE

Reinforced Impact Safety Evolution (RISE) or Realized Impact Safety Evolution is the brand name of Mitsubishi's patented safety body construction system. It was first introduced in the 1996 Mitsubishi Galant. Initially designed to improve passive safety, the system has subsequently been developed to electronically integrate every aspect of car's active and passive safety features.

RISE is a monocoque body system that combines an energy-absorbing front and rear section with a strong, rigid occupant cell to provide protection in the event of an accident. It features high tensile steel reinforcing bars in doors and energy-absorbing material in the side pillars and roof rails. The body structure is based on a one-piece shell with high levels of bending and torsional rigidity, which provides a steel cage for the safety of both the driver and passengers.

The 2003 Mitsubishi Colt is built upon Mitsubishi’s Z platform. It features RISE safety cell with two straight rails combined with an octagonal section frame. The doors also have special steel bars running across their length to give extra impact protection. It has front and rear crumple zones, side impact bars, extended-thickness body panels and strategic spot welds that maintain the integrity of the cabin space. The Colt received a four star rating from the EuroNCAP test.

The 2007 Delica D:5 is built around Mitsubishi’s next-generation RISE unibody design (GS platform). It employs a "rib bone frame" design that uses closed-section joins to link the pillars, roof bows and underfloor cross members in hoops at the pillars and the rear door opening to realize significant improvements in body rigidity and durability as well as to provide better crashworthiness. It makes more extensive use of rust-resistant steel in the floor structure than the previous generations. Body corrosion resistance has also been significantly improved through the more extensive use of underfloor sealing and with the application of more undercoat. It uses fender panels made of a plastic resin that is flexible and can recover its shape. The switch to this material reduces weight by about 4 kg and makes the fenders more resistant to damage in minor impacts.
